Application of fractal models for determining the relationship between REEs and faults in North Kochakali coal deposit, Central Iran.

The purpose of this research is to use the Concentration-Distance (C-D) fractal model to determine the relationship between the concentrations of ƩREEs and faults in coal seams of the North Kochakali coal deposit. For this purpose, three Concentration-Distance fractal models including: ƩREEC-DDF, ƩREEC-DSF, and ƩREEC- DTF were created based on ƩREEs concentrations and the distance from dextral, sinistral, and thrust faults, respectively. Four different geochemical populations were obtained according to fractal diagrams.

Application of rhodamine B as thermochromic sensor for evaluation of performance of cold paint.

A thermochromic pigment, derived from reaction of ethylenediamine and rhodamine B known as MA-RB, has been successfully developed. This pigment showcases temperature-controlled visible color-transformation properties in both solid and solution states. The thermochromic pigment MA-RB exhibits a notable color change from light pink to rose red, triggered by thermal excitation.

Animal origins free products in cell culture media: a new frontier.

Despite the importance of finding replacements for fetal bovine serum (FBS), very few studies have focused on this subject. Historically, the use of animals and their derivatives in growth, reproduction, and physiological studies has raised several concerns. The supplementation of culture media with FBS, also known as fetal calf serum, continues to be widespread, despite its limitations in quality, reproducibility, and implications for animal welfare.

Meta-analysis: The utility of the anterior quadratus lumborum block in abdominal surgery.

Background: Regional anesthesia is routinely used in Enhanced Recovery After Surgery pathways to improve post-operative recovery times. No consensus has been reached on optimal block type. This study reviews the current literature as it pertains to the anterior quadratus lumborum (aQL) block in all abdominal surgeries, as well as its efficacy compared to the transversus abdominis plane (TAP) block.
